Lead Enrichment API — Company, People & LinkedIn Data

What is a Lead Enrichment API?

A lead enrichment API takes a starting identifier — a company domain, an email address, a LinkedIn URL, or a person's name — and returns additional data: firmographics, technographics, funding history, hiring activity, decision-maker contacts, or verified email deliverability. Most sales and marketing workflows need more than one of these lookups: company data to qualify a lead, people data to find the right contact, LinkedIn data to confirm the role, and email verification before sending.

Muapi exposes 22 lead-enrichment endpoints — company, people, LinkedIn, email, ads, news, creators, social, and web research — through the same unified REST pattern: one API key, one request/poll flow, pay-per-lookup pricing with no subscription or credit-pool minimum.

How This Compares to Apollo, People Data Labs, and Clearbit

Apollo gates data enrichment behind its Organization plan ($119/user/month) and charges 1–10 credits per enrichment call, with unused credits expiring at the end of the billing cycle. People Data Labs splits person and company data into separate credit pools starting at $98/month, priced per record ($0.20–$0.28) on top of the monthly minimum. Clearbit's standalone enrichment API was discontinued after HubSpot's acquisition — company/person enrichment now requires an enterprise Breeze Intelligence contract. Muapi charges per lookup ($0.01–$1.50 depending on the endpoint) with no subscription, no credit pool, and no contract — sign up and call any endpoint immediately.

How to Call the Lead Enrichment API

1. Pick an endpoint — by category (company data, people search, LinkedIn, email verification, etc.) using the comparison table above.
2. Submit the request. POST /api/v1/{endpoint-slug} with the identifier the endpoint needs (a domain, email, LinkedIn URL, or name).
3. Poll for completion. Check GET /api/v1/predictions/{request_id}/result until status is completed, then read the enrichment result.

curl -X POST https://api.muapi.ai/api/v1/company-enrich \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{

response = requests.post(
    "https://api.muapi.ai/api/v1/company-enrich",
    headers={"x-api-key": "YOUR_API_KEY"},
    json={"domain": "stripe.com"},
)
request_id = response.json()["request_id"]

result = requests.get(
    f"https://api.muapi.ai/api/v1/predictions/{request_id}/result",
    headers={"x-api-key": "YOUR_API_KEY"},
